  • Patent number: 10525665
    Abstract: A waved meltblown fiber web of the present invention relates to a fiber web prepared by a meltblown method and is characterized by a preparation method in which a meltblown microfiber comes in contact with collection portions having different surface velocities so as to be collected. The waved meltblown fiber web of the present invention is characterized in that: a part of meltblown microfibers reaches a low velocity collection portion so as to be horizontally layered, thereby forming a horizontal fiber layer (10); another part of the meltblown microfibers reaches a high velocity collection portion of which the surface velocity is greater that of the low velocity collection portion so as to form a serpentine vertical fiber layer (20); and the upper end of the vertical fiber layer (20) becomes entangled so as to form a wave shaped wave layer (30) forming the uppermost portion of the fiber web.

  • Patent number: 10518486
    Abstract: A method of printing a part using an additive manufacturing system includes identifying a part or parts to print and orienting a digital representation of the part(s) in a build volume. A digital representation of porous support structures for the part(s) is generated to form a digital representation of a part block of the part(s) to be printed. In the part block, a porosity of the support structure increases as a distance from an outer surface of the part increases within the print volume. The digital representation of the part block, including the part(s) and porous support structures, is sliced for printing.

  • Patent number: 10513108
    Abstract: Methods and apparatuses for making multiple three-dimensional objects from multiple solidifiable materials are shown and described. In accordance with the method, the objects are designed with variable removable support heights along the build axis so that each object has an interface between first and second materials that is the same height from the build platform. The technique simplifies the process of producing multiple three-dimensional objects from multiple solidifiable materials which may have different build axis heights of first and second finished object sections so that the sources of solidifiable materials need only be switched once during the building of multiple objects.
